Information storage and retrieval
Abstract
Identifying information is stored or recorded on a recording
element and camouflaged by recording the identifying information on
a recording element through an information transformation medium
such as a lenticular plate and then camouflaging the recorded
information by recording the information on the same recording
element through the information transformation medium, disposed at
a different position than that used in recording the identifying
information thereby concealing the identifying information recorded
on the recording element. The concealed information thus storaged
or recorded can be identified by observing the recording element
through the same information transformation medium at the same
position used in the initial recording of the identifying
information.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of storing or recording
an identifying information on a recording element and camouflaging
it and also a method of retrieving the concealed identifying
information thus recorded.
SUMMARY OF THE INVENTION
The present invention provides an information storage and retrievel
system in which an identifying information for, e.g., an ID card
such as credit card, is recorded on a recording element and then
the recorded information is concealed or rendered indiscernible by
camouflaging the information to provide a scrambled record of the
identifying information which can not be discerned by the naked eye
and further the concealed information can be discerned using only a
specific retrievel or reproduction technique. By employing such a
system as described above, the use of the ID card, etc., in an
unauthorized manner can be prevented.

DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1 of the drawing, an identifying information of an original
medium 1 is recorded on a recording element 4 such as a
photosensitive element (e.g., a light sensitive silver halide
material), an electrophotosensitive element (e.g., as disclosed in
U.S. Pat. No. 2,297,691), etc., through an optical system 2 for
forming an image, and an information transformation medium 3 having
the ability to focus the image, such as a lecticular plate. When
the recording element 4 is a photosensitive element, the recording
is conducted using a photographic image exposure, while when the
recording element is an electrophotosensitive element, the
recording is conducted using an electrophotographic image-forming
technique.
Also, a magnetic recording element and magnetic recording system
can be employed in this invention. For example, binary coded
identifying information can be recorded on a magnetic tape or strip
at regular intervals in a first recording step and in a second
recording step the camouflaging binary coded information can be
recorded on the same tape or strip. In such an embodiment an
information transformation medium is employed, with the information
transformation medium causing a shift of the position of the
recording on the tape or in a change the pitch of the recording,
for example, a change in pitch of one half interval.
When a lenticular plate having a cross sectional form as shown in
FIG. 1 is used as the information transformation medium 3, the
identifying information of the original medium 1 is recorded as an
image in the form of a large number of focused lines parallel to
the generating line of the lenticular plate, the image being
different from the original image of the identifying
information.
Then, information for camouflaging and concealing the recorded
identifying information is recorded on the recording element as
illustrated in FIG. 2. That is to say, camouflaging information of
a camouflaging information-containing medium 5 is recorded on the
same recording element 4 having thereon the identifying information
image. In this recording the image-forming optical system 2 and the
information transformation medium 3 are the same system and medium
used in the recording of the identifying information as illustrated
in FIG. 1. The positions of the medium 5, the image-forming optical
system 2, and the recording element 4 are the same as those of the
medium 1, the image-forming optical system 2, and the recording
element 4 in the case of recording the identifying information as
shown in FIG. 1, but the information transformation medium 3 only
is shifted in a direction perpendicular to the central axis of the
recording system to such an extent that the pitch of the lenticular
plate employed as the information transformation medium in this
embodiment does not coincide with the position of the pitch of the
lenticular plate in the identifying information recording
system.
The identifying information is, as described above, recorded on the
recording element as a scrambled image by the information
transformation medium and the scambled image thus recorded on the
recording element is further concealed completely by the
camouflaging information. Hence, the recorded image on the
recording element can not be discerned or identified by the naked
eye.
The retrievel or reproduction method of the concealed information
thus recorded on the recording element is explained by reference to
FIG. 3. Namely, the recording element 4 having the thus scrambled
records of the identifying information and the camouflaging
information and the information transformation medium 3 used in the
two recordings are disposed at the same positions as or at
corresponding positions to those used in recording the identifying
information and in these configurations the recording element 4 is
observed through the information transformation medium 3 as shown
in FIG. 3, whereby the identifying information can be observed or
discerned.
FIG. 4 illustrates also other embodiment of recording the
camouflaging information using the same lenticular plate 3 as shown
in FIG. 1 as the information transformation medium. That is to say,
in recording the camouflaging information, the lenticular plate as
the information transformation medium 3 used for recording the
identifying information is positioned in the same plane as the
original plate position so that the generating lines of the
lenticular plate at the new position are at a different angle from
that of the lenticular plate at the original position used in
recording the identifying information. The camouflaging information
thus recorded through the lenticular plate makes it difficult to
completely discern the recorded indentifying information by the
naked eye.
FIG. 5 illustrates a still other embodiment of recording the
camouflaging information according to this invention. In this
embodiment the camouflaging information is recorded on the
recording element 4 having recorded thereon the identifying
information through the information transformation medium 3 such as
the lenticular plate used in recording the identifying information
but in such an arrangement that the system composed of the
information transformation plate 3 and the recording element 4 is
at a different angle or inclination to the image-forming optical
system from that used in recording the identifying information. In
this case the recorded identifying information can be completely
concealed from the naked eye.
FIG. 6 illustrates another embodiment of an information
transformation medium 3 from that illustrated in connection with
FIG. 1 to FIG. 5. Namely, the generating lines of the lenticular
plate described above as the information transformation medium in
the embodiment illustrated in FIG. 1 to FIG. 5 are parallel to each
other but the generating lines of the lenticular plate illustrated
in FIG. 6 are truncated semi-conical lines with a common projected
apex. In recording the camouflaging information using the
lenticular plate with these radial generating lines, the lenticular
plate is rotated slightly in the same plane but around a point of
the projected apex from the position used in recording the
identifying information. In retrieving the recorded information,
the lenticular plate may be rotated back around the same point to
the original position used in recording the identifying
information. An information transformation plate of this type has
the advantage that the position for the retrievel of the concealed
identifying information recorded on a recording element can be
easily set.
FIG. 7 illustrates a further embodiment of an information
transformation medium in which a lenticular plate, in which the
generating lines are disposed with different pitches, P.sub.1,
P.sub.2, P.sub.3, - - - is used. By using the lenticular plate of
this type, the recorded identifying information becomes even more
indiscernible by the naked eye.
FIG. 8 illustrates still a further embodiment of the information
transformation medium. That is to say, in this embodiment a
so-called fly-eye lens, i.e., a lens plate 6 composed of a
plurality of small lenses disposed in plane is employed. By using
the lens plate of this type, the recording of the identifying
information and then the camouflaging information and the retrieval
of the recorded information can be practiced without changing the
relative position of the lens plate 6 and the recording element 4.
Namely, the identifying information is recorded on a recording
element 4 though an image-forming optical system 2 and a lens plate
6 having a plurality of small lenses in such a configuration that
the optical axis of the recording system is vertical to the lens
plate 6 or the recording element 4. Then, the camouflaging
information of the medium 5 is recorded on the recording element 4
through the image-forming optical system 2 and the lens plate 6 in
such a configuration that the optical axis through the camouflaging
information medium 5 and the image-forming optical system 2 to the
lens plate 6 is different from that used in the system of recording
the identifying information. The identifying information thus
recorded on the recording element and then camouflaged by the
camouflaging information through the lens plate can be retrieved by
observing the record using the optical axis at the same angle as
that used in recording the identifying information. In addition, in
the embodiment illustrated in FIG. 8, the identifying information
can be recorded in the optical axis used in describing the angle of
recording the camouflaging information in the above example and
then the camouflaging information can be recorded in the axis
vertical to the lens plate 6.
As described above, for concealing the identifying information as
the scrambled record thereof, the camouflaging information is
further recorded on the scrambled record to provide a concealed
record of the identifying information which can not be discerned by
the naked eye and only the identifying information thus recorded
can be discerned using a specific retrieval manner only. Thus,
according to the present invention, the unauthorized use of ID
cards, etc., can be prevented and further a simple retrieval or
reproduction means can be provided.
Alternatively, the sequence of recording steps can be reversed, if
desired, with the camouflaging information being recorded first and
then the identifying information recorded.
As will be apparent to one of skill in the art, various changes can
be made in the above embodiments without departing from the scope
of the invention herein involved, and it is intended that all
description in the above disclosure and the accompanying drawings
shall be interpreted as illustrative and not limiting.
